A little bit about the biggest urban forest in the word. Today, I gonna tell a litte bit about a place that I love, Floresta da Tijuca “Tijuca´s Forest”. This forest is the biggest urban forest in the world, and for me, it is the main touristic attraction in the Rio de Janeiro city. In this region, there are many tracks and waterfalls that a lot citizens and tourists visits , and the most important brazilian spot touristic is located there, Cristo Redentor. In spite of been well known, few people knows that this forest was reforested in the nineteenth century by the monarchy. During the 19th century, farmers cut trees to open space for sugar and coffee industry, however with overtime, the rivers that flows and used to supply the city were drying. At that, Dom Pedro II, ordered the reforestation of these lands, with the objective to recuperate the water supply. In the beginnings, native species were planted, a chief police coordinate the mission, and six slavers cultivated more than one hundred thosand trees. Afterward, landscapers projects were implemented, originating lakers and beautiful gardens. Unfortunately, some foreigners species were brought, as a jackfruit from India, nevertheless they spread rapidly and destroy native plants. Nowadays, o “Parque nacional da Tijuca” (Tijuca National Park) is a pungent forest that connect neighbors and people, his view and beauty show us how we can conciliate a big city with a environmental development, without these green area, Rio de Janeiro would be more polluted and graceless. We must thank the pioneers that rebuilt the ecosystem and preserve this legacy for our descendants.

I am not a scientst, I am just a artist that like to consume a vast variety of knowledge, and permafrost fascinating me so much. Sometimes I imagine how beatiful would be if permafrost not just preserve dead animals, but even extinted languages and extermitaded civilizations. Surely this a hypothesis in a surrealist narrative, however it is intriguing how our current society would react to this new. First, it is incalculable the lost wisdom with these languages, hundred simply diseppear during colonization in the americas. If was possible to rescue it in the permafrost? Indegenous would be grateful for this offering, and they would be capable to restitute self-esteem in the oratory. Second, it is possible to rescue lost traditions? Same as secret router, abandoned behaviors, choreography, cuisine and many other aspects that characterize a culture, in addition, absording all this today? It would be beatiful and touching to witness these events. if you could correct this text,,,, thanks so much..
